The management shuffle comes as Mattrick, who took over for Zynga's founder Mark Pincus as CEO last month, tries to get the company back on track after it has lost users of its online games. Mattrick said the three executives are leaving to pursue "other interests."

"Each person has contributed to the growth of Zynga," he wrote. "We appreciate their contributions to Zynga’s first chapter and wish them well in their future endeavors."

Mattrick said last month that he expects two to four quarters of "volatility" as he attempts to turn around the company, which has lost ground to competing makers of social and mobile games such as King.com, of "Candy Crush" fame.

Tuesday's announcement marks the company's first major restructuring move since Mattrick took over.

"With the above in place, I believe that we will have the best chance to grow, build a world class executive team and culture, establish cadence and really become committed to important priorities and opportunities for our long term success," Mattrick said.
